Each of the identical sections formingthe fire bowl includes an arcuateportion, the lower edge of which, 60,is seated in the groove 61 in thegrate plate and the upper edge of which terminates in an outwardlyflared lip 62 which terminates immediately adjacent the inside casing 25at a point considerably remote from the top. Each section includes theelongated openings 63 which form a perforated fire bowl. Each sectionhas a butt joint connection with its adjacent section as indicated at64. Each section at its top portion has a butt joint connection as at65.

Each outwardlyflared portion at one end includes a groove 66 and at itsopposite end includes a lug 67, the groove of one section receiving thelug in interlocking relation of the adjacent section. The sectionallining arrangement in addition to permitting the multiple manufacture ofidentical parts, also is of such a character that-each liner section maybe supplied to the interior of the casing, mounted therein, and

operatively associated with the other linersections without requiringthe removal of the two shells 25 and 26.- The liner is passed into thecombustion chamber through the filling openmg. l

The before mentioned flaring of thev sections of the fire bowl providesspace between said sections and casing 25 which forms an air passage,

from the ash chamber into the fire bowl through openings 56 of grate 14and openings 63 in liner sections, thus providing air for dryingpurposes during the timeincinerator is being filled.

When readily combustible waste is to be burned, the cover. 22 is openedand the material supplied to the fire bowl, and the material ignited.The air is supplied to the material through the openings 52 and 53 andthe material burns. The fire will not choke or smother because thechannel type flue is provided in the liner section that ispositioned'beneath the pipe openin 57. As stated the two casing members25 and 26 form a heat insulating air chamber around the fire bowl andthe portion of the device immediately thereabove. The flaring of thesections of the fire; bowl provides that material deposited within thesame, which would probably be conical shape by reason of the positioningof the opening, will automatically center in wardly in passinginto thefire bowl as the material therein burns. If small enough, the ash fallsthrough the grate openings. Portions too large to fall through arepermitted to drop into the ash pan therebeneath by the outward slidingof the grate 40. Material that rests upon the side edges of the grateplate may be knocked through the opening by the insertion of a stick orpoker through the opening 21 in the top.

When the aforesaid mechanism is to be used for, wet materialsuch asgarbage and the like which requires a relatively high heat for dryingprevious to incineration, and which heat is not obtainable from thematerial to be burned, a burner construction is embodied. Such a burnerincludes a T fitting or the like 70, with a branch opening 74 in thecasing 24 and said nozzle con-' stitutes a pilot light for the burner.The opening 74 provides passage for pipe 76 and also permits the air topass through and into the air for combustion purposes.

The main burner supply is controlled by the valve 75 and the line 76therefrom is joined to a pair of oppositely extending lines 77, each ofwhich suppliesa nozzle supporting supply line 78, herein shown providedwith a plurality of upwardly extending nozzles 79. The lines 78 andnozzles 79 are arranged in parallel relation. Each pipe 78 is capped asat 80 and the cap includes an eye 81 integral therewith. A yoke 82having the plate portion 187 and arm portions 83, each provided with anopening 84, is supported by bolt 86 which passes through plate 187 andchamber beneath the grate plate for supplying the grate plate at 85. Apin 87, or the like, piv-- otally connects the eye 81 with the yoke 82.

The free and closed ends of pipe 78 may. be mounted together. as theother ends similar to 77, and pipe or pipes 77 may also be provided withnozzles 79 thus materially increasing heat for drying.

The pilot light is merely a convenience for lightingthe burner deviceornozzle 79. ,The pilot light may be omitted and the burners may be 7lighted by applying a lighted taper to them through the ash dooropening.

a 'n the inside of lower casing 24 are secured two ash deflectors 99 ofsheet steel, one on the right side and one on the left side of the ashchamber. Deflectors are of such a shape that the outside fits the curvedsection of casing 24 at a point just below where casing 24 meets grate14. 4 The plane of the deflectorsslope downward and terminate on a linebetween the burner arm 78- and ash pan sides 46 and parallel to arm 78.

Ashes dropping through slots 68 of liner and thus through openings 56 ingrate 14, also through openings 53 in grate 14, are deflected into ashpan 45.

The invention claimed is:

1. In an incinerator, the combination of a top plate having a refusefilling opening, and a smoke outlet, a closure for said opening, a baseplate, an intermediate grate plate secured in spaced relation, an outerupper casing between the top plate and grate plate an outer lower casingbetween the dumping plate and base plate, said intermediate platehavingaperiphera1 series of apertures, a peripheral, laterally apertured firebowl, Supported by the intermediate,

plate within the peripheral arrangement of the apertures and terminatingin an outwardly and upwardly directed rim, an upper inner casinginterposed between the two upper plates and positioned without theperipherally arranged apertures, said rim terminating in close proximityto the inner casing, andat an appreciable distance below the top plate,and a stack-like extension extending from'the rim and in alignment withthe smoke outlet but terminating slightly short thereof, the extensionpreventing refuse from passing downwardly between the bowl and innercasing but readily permitting smoke passage upwardly therethrough, andby reason of its termination below the top permitting smoke passagelaterally to the outlet of the gases and smoke rising vertically fromthe burning refuse, the grate plate being interiorly apertured toprovide a vertical supply of air to the drying burning refuse,

the peripheral apertures and lateral apertures also cooperating tofacilitate drying and burning of said refuse.

2. A device as defined by claim 1, characterized by the addition of ashand non-combustible refuse guiding means depending from the intermediateplate for directing discharge to an ash drawer, and means provided insaid intermediate plate for dumping the ash and non-combustible refuse.
